Abstract: ABSTRACT             APPARATUS FOR PATTERN RECOGNITION      A temporal  sequence  of  signal  vectors  X (e.g. generated from a speech signal) is supplied in parallel to elements 101 in an array each of which (after training of the array)  provide an output ? indicating the vector's similarity to a reference vector.   Persistence is  (115) built  into  the  elements  so  that  signals  forming  a "trajectory" within the array, corresponding to an input sequence  are  simultaneously  available  for  recognition (unit 110 or, preferably by a further such array).  Arrays may be cascaded to allow for longer sequences.

Granted: 1992-10-13
Abstract: ABSTRACT OF THE DISCLOSURE           A hinge with an adjusting system, of the type in which a hinge arm can be secured to a base plate by means of at least one adapter.  The hinge arm incorporates holes through which the adjusting and attachment screws pass. The adapter can be installed in the base plate and can be locked by means of a rocker lever supported on the adapter so as to be able to swivel.  The adapter is U-shaped and has two side arms that enclose the base plate at the sides.  Both of these side arms of the adapter lie with no clearance on the base plate, and the material of at least one of said side arms is weakened at at least one place.  The adapter is installed at the front by means of a cross pin in a notch in the base plate.  The shape of the notch corresponds to a casing section of the cross pin and the cross pin is accommodated without any play within the notch.  The generators, or the mid-line longitudinal axis of the notch and of the cross pin lie unstressed at a flat angle (.alpha.) relative to each other.

Abstract: Abstract An improved tubular joint between two tubular members having  their  mating  ends  with  inner  sealing  surfaces tapering outward in the direction toward the other tubular member and with a sealing ring having outer sealing sur-faces  for  engaging  the  inner  sealing  surfaces  of  the tubular members.  The improvement lies in the provision of a insert sleeve having a tapered portion and a tubular portion, the insert sleeve is cold forged in place over a damaged sealing surface of one of the tubular members and has a tapered inner sealing surface for sealing with the outer surface of the sealing ring.  This improved joint is particularly useful in subsea wellheads.  The tight grip-ping and sealing engagement of the insert sleeve within the tubular member is augmented by grooves within a recess on the interior of the tubular member being repaired or sharp annular teeth around the exterior of the tubular portion of the insert sleeve.  In a modified form of the invention, the insert sleeve includes external sharp teeth which when cold forged into a housing recess will dig into the  recess  surface  to  provide  the  tight  gripping  and sealing engagement.   Further a test port is provided to determine the effectiveness of the sealing engagement of the insert sleeve within the housing.

Granted: 1993-04-27
Abstract: ABSTRACT OF THE DISCLOSURE               A connection device for use in securing an end of a corrugated pipe to a fitting such as a terminal box connector or a pipe-to-pipe coupling has an array of fingers extending axially from an annular ring, for insertion into the fitting.  Enlarged head portions at the inner ends of the fingers serve to engage the ribs or corrugations on the pipe outer surface, when a pipe is inserted therepast, and also provide a differentiated camming action to secure engagement of the head portions with a corrugation of the pipe and to prevent withdrawal of the pipe from the fitting.  The fitting with which the device is combined also has an axially extended inner peripheral seat against which the pipe corrugations seat, to preclude passage of concrete between the pipe and the fitting.

Abstract: Abstract Fitting with a handle for operating the lock follower of a lock fitted in a door or the like The invention relates to a fitting with a handle for operating the lockfollower of a lock fitted in a door or the like. The fitting comprises a fixing device for its fixing to the door or the like and for rotary mounting of the handle, which device is passed through by an operating rod mounted without play in the follower and inserted into a receiving opening of the handle. The receiving opening is so formed that it -going from a datum position - transfers directly to the operating rod rotary movements of the handle taking place is a first direction of rotation but is without influence on the operating rod with rotary movements of the handle taking place in the opposite direction of rotation, commencing from the datum position, at least within a predetermined range of rotation. The fixing device comprises a transmission mechanism which converts rotary movements of the handle, taking place in the opposite direction of rotation, commencing from the datum position, into rotary movement of the operating rod likewise taking place in the first-mentioned direction of rotation. Accordingly it is possible to turn the follower in the sense of rotation necessary for opening the lock both through right turning and through left turning of the handle.

Abstract: beta -Sitosterol is isolated in yields over 90% as a hydrate from a steroid mixture, separated from the neutral fraction of raw soap, by dissolving the said mixture in a solvent and precipitating the hydrate by addition of water. Thus, the process may be operated by heating the said mixture with a solvent, e.g. acetone or isopropanol, and adding water. When the mixture is cooled to 15 DEG C or below, a product rich in  beta -sitosterol crystallizes out as a hydrate. This product may contain, in addition to the  beta -sitosterol, at most 4% alpha -sitosterol, 7% campesterol and 0.5% other impurities.
